| Abstract | This study assessed the cytogenotoxicity of water samples obtained at the discharge site and about 1.5 km downstreamof the discharge site of a textile factory along Challawa River, Kano, Nigeria. After physicochemical and microbialcharacterizations, water samples were used to grow 20 Allium cepa bulbs divided into two equal groups for 72 hrs. A controlgroup was similarly conducted, but was grown over deionized water. Root-tips of the bulbs were then examined for chromosomalaberrations. Physicochemical analysis showed that the levels of Ca, Cd, Cr, Pb, DO, BOD, COD, turbidity, and nitrate in bothwater samples were not within WHO standards. Only the bacterial loads of samples from 1.5 km distance were abnormal in themicrobial analysis. A significant (p<0.05) reduction in mitotic index and bi-nucleated cells, sticky and vagrant chromosomeswere observed in the treated bulbs. These findings showed that the water samples could be toxic. |
